Installation and
Operation Instructions
1.0 Scope
This document details the installation and operation requirements for Applied
Electronics Power Monitoring System. These Instructions are provided for model
PM-360 rack mount unit.
2.0 General
Applied Electronics Power Monitoring System consists of a 3 space rack
mountable chassis with user interface on the front panel (see Figure 1). The PM360 provides the capability to monitor the voltage and current on three input
power phases as well as the phase to phase voltages, ground to neutral voltage
and frequency. The phase to phase voltage displayed is selectable via the
control knob on the front panel. Included with the panel are 3 current sensing
coils and a power wiring harness.
NOTE: Due to the wide variety of mounting locations and configurations
mounting hardware is not included. Please contact Applied Electronics if unsure
of mounting options.
Each PM360 is provided with a standard one-year warranty for parts and labor.

4.0 System Installation
The following sections detail installation and wiring procedures for the PM-360.
4.1 Current Coil Mounting
Included with the PM-360 panel are three current coils (see Figure 2). These
coils measure the current draw on the three main power lines in a system. It is
recommended that these coils be mounted securely to
the base of the rack or if rings are provided, tie
wrapped to power cables. Once mounted the
individual mains cables can be passed through the
hole in each current coil. It is recommended that only
one main cable be passed through the coils however
multiple cables can be used only if the phase and
current direction being measured are the same. For
example three input cables from phase A input may
pass through a coil but two cables from phase A and
one cable from phase B may not. Mixing phases or
directions will result in incorrect current readings.

4.2 Panel Mounting
Each PM-360 unit is intended to be mounted in a standard 19” rack enclosure
and utilizes 3 rack units of space (5.25” high).

4.3 Wiring Connections
WARNING
VERIFY THAT THE SYSTEM BEING MODIFIED IS
DISCONNECTED FROM ITS INPUT POWER PRIOR TO
MAKING THE FOLLOWING CONNECTIONS. FAILURE TO
DISCONNECT POWER MAY RESULT IN INGURY OR DEATH
The PM-360 comes with a 56” wire harness that is used to connect the unit to the
three mains voltages, neutral, ground and the current rings. The connections to
the back of the panel are made using the terminal screw block (see Figure 3).
The connections to the current coils are made using the two screws on top of
each coil or if rings are provided, they are pre-wired to harness. The connections
to the three hot phases, neutral and ground should be made so that they are
secure.
WARNING
The sensor lines MUST NOT be connected in any manner that would cause
them to carry current to any load other than the PM-360 panel.

5.0 PM-360 Operation
Each PM-360 is calibrated before leaving the factory and has been designed to
deliver years of maintenance free service. When powered up the monitor will
constantly display the current voltage and current draw on each of the three
supply phases as well as the ground to neutral voltage and frequency. The three
phase to phase voltages can be selected at any time using the three position
rotary switch on the front panel.
